I just spent 40 minutes updating my blog index to include all the non-Emacs News and non-weekly/monthly-review posts since April 2017. I had kept a blog index as a way to quickly organize my posts into finer-grained categories without mucking around too much with WordPress. Updating it was pretty easy since I had built an Org Mode list view into my theme eight years ago. A URL like https://sachachua.com/blog/2020/?org=1 gets me a list like:

- [[https://sachachua.com/blog/2020/01/2020-01-06-emacs-news/][2020-01-06 Emacs news]] 
- [[https://sachachua.com/blog/2020/01/weekly-review-week-ending-december-13-2019/][Weekly review: Week ending December 13, 2019]] 
- [[https://sachachua.com/blog/2020/01/weekly-review-week-ending-december-20-2019/][Weekly review: Week ending December 20, 2019]] 
- [[https://sachachua.com/blog/2020/01/weekly-review-week-ending-january-3-2020/][Weekly review: Week ending January  3, 2020]] 
- [[https://sachachua.com/blog/2020/01/weekly-review-week-ending-december-27-2019/][Weekly review: Week ending December 27, 2019]] 
- [[https://sachachua.com/blog/2020/01/2020-01-13-emacs-news/][2020-01-13 Emacs news]] 
- [[https://sachachua.com/blog/2020/01/2020-01-20-emacs-news/][2020-01-20 Emacs news]]
...

which is easy to narrow to in Emacs with narrow-to-region (C-x n n) and filter with flush-lines to get rid of all the fairly routine weekly reviews and Emacs news posts. Then I could use my/org-file-blog-index-entries from my Emacs config to file things to the high-level trees, and (while t (my/org-move-current-item-to-category (completing-read "Category: " (my/org-get-list-categories)))) to file things within a list.

Yay Emacs!
